The Frame-shearing Wall Structure Earthquake Resistance Design Calculation And Simplifies The Analysis

The frame - shearing wall structure is composed by the frame and the shearing wall of anti-lateral force structure, because the shearing force wall anti-side rigidity is much bigger than the frame anti-side rigidity, therefore their synergism already may provide the overall structural big anti-lateral force, Also used the portal frame structural to be possible to provide big spatial the superiority. Therefore this kind of structure system integrity well, the rigidity big, the lateral deformation small, the earthquake resistance performance is good, easy to satisfy in the high-level structure the present national standard limitation value request, But obtains the widespread application. But regarding this kind of structure system simplification analysis still is in the simple rigidity superimposition.By using finite element method, Carries on the overall structural mechanical analysis using ANSYS and the Matlab software to the frame - shearing wall structure,the natural frequency(period) and vibration mode are computed sequentially for the frame-shearing wall structure. Based on the dynamic properties, we can study the stiffness characters of this structure. Carries on the structure simplification according to the rigidity distribution situation, From this derived the frame - shearing wall structure equivalent simplification model just to link the system and the articulation continually system,again according to the equivalent principle that the dynamic properties of the simplified model and the entity structure should keep be consistent, an approximate computing formula for estimating the entity structure is derived,associated numerical seismic response analyses are carried out. Finally, by comparing the results with that of entity structure, all obtained the very good result,the rationality of the simplified model is validated.In order to take the advantages of the effective finite element analysis and the powerful matrix operations. Through compiling M file technique in Matlab and Ansys mixed programming, the method of realization and program for various interface connections have been given in this paper. And the article has summarized some merits and shortcomings for various methods described. By taking use of ANSYS Parameter Design Language (APDL) and powerful mathematic calculation capacity and graphic capacity of Matlab, we can accomplish the integration of earthquake resistance of engineering structure initially and offer a better programming way in project development.The calculation results show that the method can optimize structure form and improve the security and economical efficiency, and this will provides a practically valuable reference to engineering design.
